We installed WebLink 8.2 on two new servers.  Each is giving the same error when we browse to Login.aspx. (or About.aspx)

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

Config Error

Config Source
290:       <remove name="ScriptResource" />
291:       <add name="weblinkrsshandler" path="*.rss" verb="GET,HEAD,POST" type="Rss.WebLink8RSSHttpHandler" preCondition="integratedMode" />
292:       <add name="weblinkpdfhandler" path="*.pdf" verb="GET,HEAD,POST" type="System.Web.UI.PageHandlerFactory" preCondition="integratedMode" />

Line 291 is in Red

Why would a fresh installation give an error from config file parameters?
Is there something missing from the installation?

Thanks!
